Title: Olefinically-usaturated organic polymers
IPC: C08F8/00
Filed: 1973-10-26
Abstract: 1410697 Semi-telechelic unsaturated prepolymers UCB 26 Oct 1973 49938/73 Heading CP3 Pre-polymer compounds having semi-telechelic olefinic unsaturation, and containing more than one unsaturated group, correspond to the formula in which V is the radical of a compound containing at least one polymerizable group and another group capable of reacting with the functional groups of the compounds from which radicals W and Y are derived; W is the radical of a chain transfer agent RSH, R being an organic radical containing at least one hydroxyl or carboxyl group; X is the radical of a compound containing a polymerizable group; Y is the radical of a compound containing a polymerizable group and also at least one hydroxyl, carboxyl acid anhydride or epoxy group; y is zero or an integer from 1-10; x is the number of moles of X necessary to give the chain a molecular weight of 1000-10,000; H is the hydrogen atom detached from the chain transfer agent RSH; arid the X and Y radicals are distributed statistically along the polymer chain in accordance with reaction kinetics. The polymers are prepared by (1) polymerizing monomers containing X radicals, or monomer mixtures containing X and Y radicals, in the presence of RSH, and (2) reacting the product with compounds containing V radicals. When W contains carboxyl groups and Y (if present) contains carboxyl or acid anhydride groups, V will contain hydroxyl or epoxy groups. When W contains hydroxyl groups and Y (if present) contains hydroxyl or epoxy groups, V will contain carboxyl, acid anhydride, acid halide or transesterifiable ester groups; alternatively, Y may first be reacted with a diisocyanate-to form a product containing a free NCO group with which an unsaturated hydroxy compound may then be reacted. In Examples 9-14, 16, 17 and 28, acrylic acid, maleic anhydride or, in sequence, tolylene diisocyanate or isophorone diisocyanate followed by 2-hydroxyethyl acrylate or methacrylate, are reacted with hydroxylcontaining polymers prepared using 2-mercaptoethanol or glyceromercaptan as chain transfer agent, the monomers or monomer mixtures being methyl methacrylate, methyl methacrylate / 2- hydroxypropyl methacrylate, methyl methacrylate / ethyl acrylate / 2- hydroxyethyl acrylate or methacrylate, and ethyl acrylate / 2 - hydroxyethyl acrylate. In Example 21, allyl alcohol, 2-hydroxyethyl acrylate or glycidyl methacrylate are reacted with a carboxyl-containing polymer prepared by copolymerizing ethyl acrylate and acrylic acid in the presence of thioglycolic acid as chain transfer agent. The above pre-polymers, either as such or dissolved in unsaturated monomers, have a variety of uses, e.g. as paints of various types, coatings, varnishes, and moulding and casting compositions. These uses are illustrated in Examples 22-27, using a variety of unsaturated monomers and other additives such as pigments. Examples 9-14, 16-21 and 28 also describe copolymerization of the pre-polymers with monomers by various techniques.

IPC: C25D13/22
Filed: 1967-11-08
Abstract: 1,247,731. Electrical deposition of insulating material. E.M.I. Ltd. Oct. 23, 1968 [Nov. 8, 1967], No. 50821/67. Heading C7B. Insulating particles 8 e.g. of a phosphor such as zinc silver sulphide are deposited on an insulating support 2, e.g. glass or a mica sheet, by providing one surface of the support with a thin electrically conductive film 4, e.g. of antimony, electrically connected to a further electrical conductor, e.g. ring 3, which can be seen from the opposite side of the support, placing the insulating support between an anode 5 and a cathode 6 in an electrically conducting solution, e.g. of aqueous zirconium nitrate in iso-propyl alcohol, containing the insulating particles in suspension so that the conductive film faces one of the electrodes and the further conductor faces the other electrode and applying a P.D. between anode and cathode to cause the particles to be deposited on the conductive film. When a single layer of particles has been deposited current flow ceases and the coated support is then washed in water which removes most of the antimony film. Thereafter the coated support is coated with a nitro-cellulose lacquer film and aluminized, and thereafter baked at 400C., removing the lacquer film and the remaining antimony. Instead of antimony aluminium may be used for the conducting film. To improve the deposition a stainless steel grid may be disposed between the anode 5 and the support 2, and in an alternative arrangement instead of ring 3 an annulus of conductive material may be provided on the face of the support directed to the cathode 6.

Filed: 1967-11-09
Abstract: 1,169,058. Closure dispensers; portable containers. POLY-PAK CORP. OF AMERICA. 9 Nov., 1967, No. 51023/67. Headings B8D and B8T. A container for liquids consists of a body portion 10 and a closure which comprises of a cup-shaped member 12 having a top wall 13 and a side wall 14, and a relatively rigid collar 16 rotatably mounted on the member 12, axial movement being restricted by bead 15 seating in annular groove 22. The inner surface of the collar 16 is elliptical in cross-section and the outer periphery of member 12 has substantially the same shape. When the two parts are assembled and the major axes of the ellipses are coincident aperture 18 is open. In such a position the aperture has a generally double convex shape with the chord joining the sharp corners at right angles to the major axis, Fig. 4 (not shown). Rotation of the collar through 90 degrees deforms member 12 and closes the aperture. A definite sealing force between edges 19 is ensured by having the maximum width (c) of the aperture slightly less than the difference between the major and minor axes of the ellipses. The cup-shaped member may have a circular cross-section, in such a case the peripheral lengths of the circle and the ellipse of the collar would be substantially the same.

Title: Warp tension controller
IPC: D03D49/04
Filed: 1975-12-15
Abstract: 1526969 Warp tension controller RUTI-TE STRAKE BV 15 Dec 1975 [25 Feb 1975]  51290/75 Heading G3N [Also in Division D1] A warp tension controller for a loom has a comparator 3 receiving a warp tension signal 1 and a reference 2. The comparator output feeds one input of an operational amplifier 4, having a PI feedback loop using capacitor 8 and resistors 6, 7, which controls tension at output 5. When the loom turns at low speed, e.g. during replacement of the warp beam, ganged switches 15, 16 are moved from their shown position whereby capacitor 8 and resistor 6 are disconnected from the feedback circuit and connected to output terminal 10 of a memory (not shown) having input 9 which may comprise a voltage divider with a servomotor driver adjustable tap. Resistor 17 is then connected across the feedback circuit to limit amplifier gain. When the loom stops, ganged switches 11, 12 are moved from the position shown whereby capacitor 8 is disconnected from the amplifier feedback, the amplifier then acting as a proportional controller and its output is connected to memory 10. This is claimed in Specification 1526968. When the loom returns to full speed, the use of the memory 10 is stated to prevent transient conditions.

Title: Bubble domain switch and rewritable decoder
IPC: H03M7/00
Filed: 1974-12-05
Abstract: 1483109 Magnetic bubble switching device INTERNATIONAL BUSINESS MACHINES CORP 5 Dec 1974 [28 Dec 1973] 52614/74 Heading H3B A magnetic bubble switch, particularly for programmable decoders, comprises means 16 to hold a control bubble captive so as normally to divert an incoming bubble 10 along a first path Y, and means 18, D to inhibit the effect of the control bubble and switch the incoming bubble along a second path X. The control bubble is placed on a permalloy disc 16 or in an ionimplanted region by energizing conductor D when the bubble generated at 20 is at position 3 on Y-bar 12. Data bubbles subsequently arriving at 10 follow path Y by mutual repulsion which may be overcome to switch the bubbles to path X by passing current through conductor D. A switch without the control bubble allows bubbles to pass along path X regardless of whether current flows in conductor D. A series of switches in respective propagation paths may therefore be operated in coded fashion to allow through transmission of bubbles or diversion to annihilators or other circuit areas (Fig. 6, not shown). Re-programming is effected by collapsing all bubbles and positioning control bubbles at selected switch positions.

Title: Article handling apparatus
IPC: B65B43/56
Filed: 1971-11-15
Abstract: 1404938 Conveying cartons through a series of work stations METAL BOX Ltd 1 Nov 1972 [15 Nov 1971] 52900/71 Heading B5A Articles 15 (e.g. cartons to be filled or folded) (Fig. 1) are moved past a series of work stations 14, and are held in predetermined position for a set period at each station, by pairs of pawls 82, 83 (Fig. 6). The cartons are initially engaged between members 36, 37 (Figs. 1 and 2) which swing from an inoperative position X, to an operative position (full lines, Fig. 2). The members 36, 37 are then moved in the direction of conveyance to move each article by a distance only approximately equal to the distance between two adjacent work stations 14. Whilst this operation is taking place, the pawls 82 are all retracted by the action of a rod 74 (Fig. 6) activated by a cam 67 (Fig. 1) and mechanism 65, 63, 57, and drive motor 48. When the pawls 82 are moved back into operative position, the spring return action of each pawl operates to move the article into its precisely correct position. The members 36, 37, are operated by a shaft 30 which has a reciprocating movement derived from a lever 42 oscillated by a cam on a shaft 46 connected to the motor 48. The shaft 46 also drives a cam (56) (Fig. 4 not shown) to oscillate an arm 54 (Fig. 3). This operates through a gear 51 to engage a slidable toothed gear portion 50 on the shaft 30 which carries the article moving members 36, 37. The pawls 82, 83, may be modified so as to deal with articles shaped differently from cartons, e.g. metal cans and fibre drums. The pawls 82, 83, may be replaced by rotary cams. Instead of the articles being pushed back into precise position from an over run position (as shown), the arrangement may be such that they are pushed forwards into the final position. The pawls 82, 83, may operate on the tops of the articles instead of on the sides (as shown). The members 36, 37, may act on the top and bottom of each article.
